day), in order to prevent the possibility of panel disfiguration, unstable
operation, or damage to the internal components.
• Do not place vinyl, plastic or rubber objects on the device, since this
might discolor the panel.
• When cleaning the device, use a dry and soft cloth. Do not use paint
thinners, solvents, cleaning fluids, or chemical-impregnated wiping
cloths.
• When turning on the AC power in your audio system, always turn on the
power amplifier LAST, to avoid speaker damage. When turning the
power off, the power amplifier should be turned off FIRST for the same
reason.
• Be sure to observe the amplifier’s rated load impedance (see
“Specifications”), particularly when connecting speakers in parallel.
Connecting an impedance load outside the amplifier’s rated range can
damage the amplifier.
• When connecting the speakers with high impedance, be sure that the
total rated input capacity of the speakers does not exceed the output
power of the amplifier.
• When using a high-impedance speaker connection, make sure the audio
signal is passed through an 80 Hz or above high-pass filter before being
input to the speakers.
• Do not swing the speaker by its carrying band.
• Do not place the speaker face down with the grille attached, as
deformation of the grille may result.
• When placing the speaker face down, always place it on a flat and
smooth surface.
• Do not touch the speaker driver unit.
● Protective circuit
This speaker system has an internal protection circuit that shuts off the
speaker unit when an excessive input signal is applied. If the speaker unit
emits no sound, reduce the volume level of the amplifier immediately. The
sound will return automatically in several seconds.
● About this manual
• The illustrations as shown in this manual are for explanation only, and
may appear somewhat different from your device.
• The company names and product names in this manual are the
trademarks or registered trademarks of their respective companies.
• Do not insert your fingers or hands in any gaps or openings on the device
(ports).
• Do not rest your weight on the device or place heavy objects on it.
• Do not operate the device if the sound is distorting. Prolonged use in this
condition could cause overheating and result in fire.
• Do not pull the cables connected.
• When choosing a power amplifier for use with this device, make sure that
the output power of the amplifier is lower than the power capacity of this

Ensure that the strength of the ceiling rail is sufficiently strong.
Pre-installation (Preparation of the Cable)
Use stranded wire for cables attached to the ceramic terminal. Strip
their insulation as shown in the figure and connect them.
About 7 mm (0.3")
Note
Do not plate stranded wires by solder. Doing so will cause the wire to
break.
Note
Prepare a cable gland of AVC part no. PGB 13.5-12B.
CAUTION
Use an appropriate tool for opening the hole. Otherwise, you may be
injured if you open the hole with your bare hands.
CAUTION
Always take measures to prevent the speaker falling down.
If the safety wire is too short, prepare another wire appropriate for the
speaker weight and installation conditions. If the wire is too long,
should the speaker fall, the wire may break as a result of too much
strain.
CAUTION
• Do not over-tighten the attachment screw. Otherwise, the
attachment screw and clamp will break.
• Do not turn any screws other than attachment screw (located
beside the U mark). Otherwise, the speaker may fall or
malfunction.
5 Set the Line Voltage/Impedance and Power
Select the line voltage/impedance (100V/70V/8Ω) and power tap for
100V/70V line distributed system, by rotating the tap selector switch
on the front side of the speaker with a flat-blade screwdriver.
4.2 Push up the speaker slowly into the ceiling, taking care not to trap the
cable.
The illustration indicates the setting at 30 W for 100 V
line and 15 W for 70 V line.
CAUTION
• The “X” position should not be selected. The 8Ω position should be
selected for 8Ω audio systems only. If the setting is incorrect, it may
cause malfunction of the speaker and amplifier.
• Make sure the amplifier is switched off before operating the tap
selector switch.
3.3 Loosen the terminal screws of the ceramic terminal with a flat-blade
screwdriver, insert the cables into each terminal and tighten the
screws. Pull on the cables to make sure they are tightly secured and
will not come loose.
